To all whom it 'may concern:

Be it known that I, J oIIN ATKINSON HUNT, a citizen of the United States, residing at Boston, in the county of Suffolk and.

Commonwealth of Massachusetts, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to an improvement in hydro-carbon burners of the type in which the oil and water are vaporized, superheated, mixed and burned as a gas.

The present invention provides for an improved vaporizing means and certain improvements in the arrangement of the vaporizing pipes to secure a more complete volatilization of the liquids and drying of the being in general for the saine nature of device as that for which I filed application No. 2f 5,428, December 5, 1904. v

It also provides for an improved mixing chamber and an improved means for taking the mixed gas therefrom, so as to avoid undesirable condensation in the bottom ot' the mixing chamber andthe flushing of the burner incident' thereto, and also provides a further super-heating of the gas at the point ot' combustion.

ln the drawings in which like letters of reference indicate corresponding parts throughout: Figure l, is a side view of the burner, l `ig. 2, a vertical longitudinal central partial section, Fig. 3, an end view of the burner, and Fig. 4, a sectional detail of the feeder.

V V1 are vaporizing tubes for oil and water respectively, each consisting ot' a plurality ot turns slightly staggered from the vertical so that each turn ot the vaporizing pipe lies close to the corresponding section `ot' the next coil. The vaporizers are conveniently formed of short sections of threaded pipe 'u joined at their ends by U shaped couplings o1. The pipe sections o are slightly sprung out of the horizontal so as to provide a continuous drain by gravity so that the inwardlyA slanting couplings o1 rest upon and are supported by the top of the said chamber M, as shown most clearly in Fig. 3. i

B is a burner tube which is tapered into the mixing chamber M directly below the entrance of the tubes V V1 therein, and is located near the bottom of said chamber so as to thoroughly drain the same. The burner tube B passes across the burner and enters a chamber' N, which is preferably arched on its upper surface to correspond to the diverging couplings el. The chamber` N, which is slightly lower than the bottom oi the chamber M, slopes slightly from its center toward its outer edges, so that there is a perfect drain from the burner tube B which enters the chamber N centrally thereof, into the burners B1 which are tapped into the chamber' N on each side of the burner tube -B and return toward the chamber M.

o1 are burner slits in the burners B1, and b2 is a drain vent in the end of the burn'- ers B1.

P is a pan in which the burner rests.

The Walls of the chambers M and N are quite thick and gather and retain heat so as to produce a uniform temperature after v the burner is in operation, which materially aids in the mixing o the gases from the oil and water vaporizers, and also in keeping hot the U shaped couplings which forni the turns in the vaporizing tubes. The mixing chamber M is relatively larger than the vaporizing tubes which enter it, and therefore allows for a'slight expansion ot' thi` gases while they are being mixed.

F is a feeder interposed inA the supply pipes S1 The feeder F consists ot a chamber F1 which is preferably formed ot glass so that observations of the feed may be made vduring the operation of the burner.

f is a pointed nipple on the inlet side off the feeder from which the oil or water drops into the chamber F1.

is a valve for governing the flow of the oil or water through the inlet The operation of the device is as follows: The valve A'controlling the oil supply is first opened and a small amount of oil'is allowed to pass through the feeder down into the burner, through which it drains, passing into the pan l) through the drain vent b2 in the end ot' the burners B1. This oil may be ignited and burned to' give the preliminaryr heat required to Start` the ap paratus. If'the mixing chamber -Mis still hot froml a previous use, the oilwill be partially, at least, volatilized and may then be lighted as a gasto start the burner. As soon as the tubes of the vaporizers become het, the water is turned on, and as the two liquids-become properly vaporized the llame increases in lheat until its maximum intensity is reached. Owing to the arrangement of the pipes, couplings and mixing chambers,.a 'hot-flame is very quickly produced, so

that the device within a few minutes ,will produce affiame of maximum intensity.

' The feeders'F can be easily adjusted to,

feed the proper amount of li uid as the rate of drip which varies with t e state of the fuel andthe degree of back pressure in the vvaporizer, can be observed through the walls of the glass chamber F1.. l

The advantage of the -burner B, locatedas it is at the bottom of the mixing chamber M, is obvious, frdm the explanation above given,"as itallows the oil to pass directly down through the mixing chamber to the pan Where .it can be ignited for the startingheat, and it-also prevents the accumulatlon of any oil or. water or deposit of impurities in the bottom ot' the mixing cha1nber.

'I have designated my'burner as a hydrocarbon burner, but it may be used with other than the regular so called hydro-can bon fuels. I find that it @fives excellent results when wood alcoholvis substituted for any of the petroleum fuels.

What I therefore claim and desire to secure by .Letters Patent, is :e

l. A hydro-carbon burner comprising a pair of substantially parallel vaporizing tubes, a relatively larger mixing chamber to which said tubes are connected, both of said tubes entering the same side of said chamber and said chamber having a flat Wall opposite to. and extending in' front of the points of entry of both of said tubesforv batliing and mixing the vapor, a vapor discharge tube extending from said mixing chamber on the same sideas and below the point of entry of said parallel tubes and op'- posite to said wall and oil and water connections for said vaporizmg tubes.
